Storm drain design calculations

Guidelines for the Design and Construction of Stormwater Management Systems Developed by the New York City Department of Environmental Protection in CHAPTER 11 STORM DRAINAGE SECTION 1101 GENERAL 1101. 1 Scope. The provisions of this chapter shall govern the materials, design, construction and installation of storm drain Drainage ditch will be designed for postdevelopment storm runoff flows using rational method flows. 2. Based on Rational Method calculations for 25yr storm, design ditch for a minimum peak flow (QP) of 25 cfs.

The objective of urban storm drainage is to optimize safe passage of vehicle traffic by collecting stormwater from the roadway, and to convey it safely to an adequate receiving body without undue risk to pedestrian Chapter 8: Stormwater Management Design Examples This chapter presents design examples for two hypothetical development sites in the State of New York. The first site, Stone Hill Estates, is a residential development near Ithaca. Home Drainage Center.

I or U. S. units. The overall procedure for design of the storm water drainage system is discussed, along with the design criteria used for the storm sewer section between adjacent manholes. The rational method is used to calculate the design storm
